Is 4 divisible by 7321694?
No; as 4 is less than 7321694 it cannot be divisible by it. Nor is 7321694 divisible by 4. There are two tests for divisibility by 4 that I can offer. First (test given in most books): If the last two digits of the number (as a number) are divisible by 4 then so is the original number. Second (much easier test): add twice the tens digit to the ones digit; if this sum is divisible by 4 then so is the original number. Using second test, for 7321694: 2x9 + 4 = 22 which is not divisible by 4, so 7321694 is not divisible by 4. The second test can be repeated until a single digit remains; if this single digit is 4 or 8, then the original number is divisible by 4. otherwise not: 7321694 → 2x9 + 4 = 22 22 → 2x2 + 2 = 6 → not 4 or 8, so original number is not divisible by 4.

Is 7 divisible by 7321694?
No; 7 is less than 7321694 so it cannot be divisible by it. Nor is 7321694 divisible by 7. There is no easy test for divisibility by 7 - most tests devised take just as long if not longer than dividing the original number by 7. One test I can offer: 1) Write the number in blocks of 3 digits from the right hand end (just like when writing out big numbers); 2) For each of the 3 digits in the blocks, alternatively subtract and add starting from the right hand end. If any digit is missing from the first block, it is taken as zero; 3) add twice the sum of the first ("hundreds) digit to three times the sum of the second ("tens") digit to the sum of the third ("ones") digit; 4) if this sum is divisible by 7 then so is the original number. For 7321694 this gives: 1) 7 321 694 2) first digits: 6 - 3 = 3, second digits: 9 - 2 = 7, third digits:4 - 1 + 7 = 10 3) 2x3 + 3x7 + 10 = 37. 4) 37 is not divisible by 7, so 7321694 is not divisible by 7.
